However, when I jar the

I think the jar thing is a red herring. In the Batik 1.5 release
there was a bug in doubleString where we did not initialize the
DecimalFormat object. This is fixed in CVS or you can call
SVGGraphics2D.setPrecision to initialize this properly.
In short:
when calling batik from another jar-file this exception happens:
java.lang.NullPointerException

This does not seem to be a classpath issue as far as I can tell, because
if I change the Class-Path attribute so that the application cannot find
the jar containing batik, I get:
java.lang.NoClassDefFoundError: org/apache/batik/svggen/SVGGraphics2D

The same problem occurs when I create an installer with
InstallAnywhere-5.5 and run the application as installed (again the
batik-sources are included in this and put in the class-path). I am run
out of ideas how to solve these, to my inexperienced eye related
problems. I hope someone can help me out in this.
Thanks
